IMPROVEMENT lN PAPER-BOX MACHINES.

Specification forming part of Letters Patent No. 178,499, dated June 6,1876; application filed April 29, 1874.

To all whom it may concern:

Be itknown-that I, McOLmTocK YOUNG, of Frederick, in the county ofFrederick and State of Maryland, have invented certain new and usefulImprovements in the Art of Manufacturing Paper Boxes, and in mechanismfor making the same, of which the following is a specification:

It is the object of my invention to manufacture paper boxes from a stripof paper by one continuous connected operation.

The subject-matter claimed will hereinafter be set forth.

In the accompanying drawings I have shown all my improvements asembodied in the best way now known to me.- Obviously, however, some ofthe parts may beused without the others, and in machines different 1nconstruction from the one herein shown. The details of construction ofsome of the parts may also be varied in some respects without departingfrom the spirit of my invention, which variations would be readilysuggested to skillful mechanics, or those skilled in the'art to which myinvention pertains, simply by reading this specification.

Figure 1 represents a side elevation of my improved machine, showing theparts in the positions they assume when the cutter is about to severj abox from the tube. Fig. 2 is a view, partly in section, on the line p pof Fig. 1,-showiug the cams for operating the printer and tube nipper orclamp, with the parts in the positions they assume when not inoperation, the cams being partly broken away to show the cam-flange bywhich the nipper is reciprocated to feed the paper tube. Fig. 3 is aview, partly in section, on the line q q of Fig. 1, showing the cams foroperating the bottom paster and cutter, portions of the frame and cutterbeing broken away to show the parts more clearly-the positions of theparts being those which they occupy just after the bottom has beeninserted in the tube.

The mechanism is mounted in a strong frame, preferably of metal, in thisinstance composed of a base-plate, A. a side piece, A and uprights A A AA A and A A main shaft or cam-shaft, B, is mounted in suitable bearingsin the uprights A A and carries cams, by which the operative partsof themechanism are actuated, as hereinafter described. Aroller, (J, ismounted upon an arm, 0 hinged to the side piece A of the frame at 0 sothat it may be turned. back when not in use. A tension-spring, c, on thearm bears upon the roller, to prevent the paper from unfirmly to the armD in this instance by the screws which hold the guide D, as shown inFigs. 1, 5, 6, and 7. A forming or folding roller, D beneath the end ofthe mandrel, (between which roller and the mandrel the strip of paperpasses,) turns up the sides of the paper, and presses them and thebottom against the mandrel, thus forming three sides of a tube. (SecFigs. 1, 5, and 7.) The paper then passes to a second forming or foldingroller, D Figs. 1, 5, and 8, which turns down one of the side flaps ofthe paper upon the top of the mandrel, forming a tube with one flap orportion remaining unfolded. The paper tube next passes beneath apaste-holder, E, Figs. 1, 5, 8, and 9, the lower end. of which isperforated or partly open, and provided with a brush, E consisting of acovering of cloth or other absorbent material, through which the paste,gum, or cementing substance penetrates. The upper side 'of that portionof the tube which has been turned down upon the 'mandrelpasses incontact with the brush, and

is thoroughly pasted. Removable type E are clamped by a set-screw, orotherwise suitably held, in a holder or frame, E (see Figs. 1, 5, and8,) which is operated as will hereinafter be described, to print thedesired words at intervals upon the tube while supported by the mandrel,so that each box, when finished, is labeled. After leaving the roller 1)the tube passes over a supporting plate or guide, E supported by an arm,F, secured to the side frame A (see Figs. 1 and 5,) between which plateand the mandrel the tube passes. This plate may have sides, or one ormore lips or flanges, f, on each side, to constitute a guide to preservethe form of the tube, which next passes to the last forming or foldingroller F, which turns down the last flap upon the pasted portion of thetube. (See Figs. 1, 5, and 10.) A plain roller, F on the opposite sideof the mandrel from that on which the folding-roller F is situated,serves to brace the mandrel and preserve the form of the tube.

It will be seen that the rollers D D F and F are all mounted uponstud-shafts supported by arms projecting from the side A of the frame,and as the forming rollers are grooved or formed with double flanges,they serve to brace the mandrel and keep it in proper positionindependently of its attachment to the frame at the front of themachine, which is important, as the mandrel is loose at its rear end.After the tube passes the roller F it enters a casing, F which preventsthe spreading or opening of the tube, and keeps the last-folded flap incontact with the pasted portion of the tube while the paste is drying.or setting. The guide or rest E before described, terminates at theroller F To insure the thorough drying of the paste I prefer to use alamp, F, the flame of which impinges against a metal plate, G, connectedwith the casing F (See Figs. 1, 5, and 11.) This heater-plate orflame-cover conducts the heat from the lamp-flame to the casinginclosing the paper tube, and insures therapid drying of the paste.Instead of using the lamp the casing may be perforated to allow air tocirculate therethrough, .or a current of air may be passed through thecasing. The tube now passes along the mandrel, between itand the casing,to a nipper or clamp,

Fig. 12. To allow the clamp to act on the tube the casing is slotted oneach side, at f f. (See Figs. 1. 2, 5, and 12.) This nipping device ispreferably constructed in-the following manner: Two corresponding sidesor plates, G G are pivoted in lugs g g on a supporting-plate, G whichis-reciprocated, as will hereinafter be.described, in slotted arms orguides G G secured to the side piece A of the frame. (See Figs. 1, 2,and 5.) The clamp-plates G are provided with female screws, into whichare screwed pointed screwpins 5 to indent the tube and prevent theslipping of the clamp when operating. The mandrel is-grooved oppositethese pins to allow the paper tube to yield, and thus prevent its beingpunctured. To prevent the points of the pins 9 from entering too farinto the paper I employ stops 9 which are formed like the pins g exceptthat their ends are blunt instead of being pointed. These stops, beingproperly set, abut against the tube when the nipper takes its holdthereon, and prevent injury of the tube. The plates are normally heldapart by a spring, 9 and have each an arm, g 9 Fig. 12, on their innerfaces, which interlock, and by means of which the plates are caused toact together when operated upon by their cam acting through an arm, G. Acam, H, fast on the main shaft B, so as to revolve therewith, (see Figs.1 and 2,) acts once during each revolution on the crank h of the arm G,;to close the clamp upon the papertube, and retain it in' such positionduring that portion of the revolution of the cam during which the crankhis ofiE the cut-away part H and in contact with the curved part h ofthe cam. At the same time that the circular part h of the cam H istraversing in contact with the crank h, a cam-flange, H, on the side orface of the plate composing the cam H, acts, by

means of an incline, W, on a friction-roller, h

Fig. 2, on a stud-shaft projecting from an arm, H pivoted in lugs 11/4on the base-plate A of the-frame.

A' stout spring, H bearing-at one end against the frame-upright A and atthe other against the pivoted arm H keeps the roller k in contact withthe cam-flange 11 As the cam-flange revolves with its incline h incontact with the roller h the clamp-supporting plate G is moved towardthe rearof the machine, as the arm H rocks in that direction, by meansof a fixed stud-arm, H Fig. 2, on the arm H and a pitrnan, gipivoted atone end in lugs on the under side of the plate G and connected at itsopposite end to the stud;

H As the main shaft, and, consequently, the

cams HH continue to turn, thesupportingplate (and also the paper tube,which is now' connected with this plate by means of the nipper mountedthereon) is moved toward the back of the machine-adistance equal to thelength of the box being'made, the tnbeof paper passing through anopening in the upright A5, Which-opening is made (see Figs. 15'

roller remains in contact with the plain portion h of the cam. Duringthis pause the box issevered from the tube, as will present ly bedescribed. The roller it next has presented to it a short incline, h, onthe camflange, which, acting through the rocking arm H stud H and pitman9 moves the plate and tube still farther toward the rear, but only ashort distance. While in this latter position paste is applied to theinner sides of the end of the tube, and the bottom inserted after thewithdrawal of the paster, as will presently be explained. In the regularorder of operation the short movement to slightly project the tube forthe application of the paste and insertion of the bottom takes place,before the tube is projected the length of a box to be formed, insteadof afterward, as just described. The printing device E during thelast-described position of the parts, is

caused to print the desired words or devices (which can be changed asdesired, as before described) upon the paper supported by the mandrel,by means of a cam,-I, upon the opposite sideor face of the platecomposing the cam H from that on which the cam H is 10- cated. Thecurved portion 1 of this cam I acts upon a crank, 1 of an arm, 1 keyedto a rock-shaft, I rocked in bearings in the ends of the guide-arms 6 Gin which the plate Gr reciprocates.

The type-holder is firmly secured upon this rock-shaft, in this instanceby a'set-screw, i, which admits of the adjustment of the holder. By thisarrangement the paper tube is printed at proper intervals, positivelyregulated by means of the joint action of the cams, .to insure each box(or each section afterward cut from the tube to form the boxes) havingthe desired printing upon it. As the cam-shaft continues to revolve, thecut-away part H of the cainH is presented to the crank h, upon whichpart the crank enters, and the spring 9 throws apart the sides G G ofthe clamp, releasing the tube. At the same time the part ll of the camIpasses from beneath the crank 1 and the shaft 1 is rocked, in thisinstance by the weight of the arm 1 thus throwing the type-holder out ofoperation, at which time it rests against a rod, 45, secured at one endto the frame-upright A, and atthe other end to the arm D This rod allowsthe printing device sufficient play to clear it from the paper, and alsoprevents the arm 1 from falling low enough to come in contact With anybut the operative part of the cam I. Shortly after the cut-away part H'ofthe cam H comes in contact with the crank it, a slope or decline, h,leading to the bottom or plain surface of a recess, H in the cam-flangeH is presented to the roller 71. which is caused to enter the recess bythe spring H and the plate G and clamp are moved forward by the rockingof the arm H ready-for the above-described operations, by the cams H, Hand I, to be repeated as the shaft B is revolved. A pasteholder, J, (seeFigs. 1, 3, and 14,) has a side projection, J at its lower end, which isopen, or provided with a partially-open or perforated bottom, to whichis'secured cloth or other absorbent material, through which the pastewill penetrate. This holder is fastened by a clamp or set-screw, j, to arock-shaft,j mounted in bearings in the ends of arms J J", whichterminate in a rod, J (shown in this instance as forked at its lowerend,) pivoted in supports j j secured/tothe base A of frame. A

cutter, K, (see Figs. 1, 3, and 13,) formed in.

A pin, f which may be provided with a friction roller, projects from therod J and is caused, by a spring, j, Fig. 1, to bear upon theirregularly-curved edge or periphery of a cam, M, which is keyed to themain shaft, and revolves therewith.. During the time the pin j? bearsagainst the regular portion M of the cam, the paster J J 1 isinoperative.

As the shaft revolves, the cut-away or recessed part m of the cam ispresented to the pin 3' the pin entering bya decline to this recess. Therod J 4 moves parallel with the face or side of the cam, and the pasterdescends, so as to bring its brush or end J in line with the tube ofpaper. When in this position, the arm'J rests upon a stop, m securedonone of the frame-pieces, to insure the paster being in the properposition, in line with the tube of paper. An arm or tappet, M fixed onthe rock-shaft j by a set-screw, now acts on a rib or projection, W, onthe face of a wheel, L, fast on the shaft B. The tappet is caused tobear against this rib by a spring, M which tends to rock the tappettoward the rod J, but is prevented from swingingit too far to ward therod by a stop-pin on the rock-shaft supporting arm J against which stopthe tappet-arm bears, and is thus held in the proper position to beacted upon and rocked by the rib on the wheel L.

This rocking of the shaft j swings the paster into the end of the tubeof paper, which, as before described, has just been slightly projectedbeyond its mandrel. Paste is thus thoroughly applied to the inside ofthe end of the tube. As the brush J enters it the tube may expand oryield slightly at its end where it is not confined, and thus accommodatea tight-fitting paster.

As the'tube projects beyond the mandrel and frame-upright, there is noliability of gumming or clogging the mandrel or the frame by any pastethat might accidentally be applied outside or slightly beyond theportion of the tube which it is desired to paste.

. As the shaft B revolves, the tappet-arm M is freed from the cam-rib mand swings vback against its stop into proper position to be acted uponagain when the revolution of the wheel brings the rib around. The pin jpasses out from the recess m upon the incline leading therefrom, and thepaster is moved first out from the tube, and then up to its inoperativeposition, the arm M being held clear of the Wheel L, and the pin 7'bearing'upon the regular part of the cam M- The parts remain in thisposition until the cams repeat the above-described operation. Thebottom-applying device now inserts the bottom in the tube, as willhereinafter be described, and afterward, the tube' having been projectedbeyond the mandrel and frame opening the length of a box, as beforedescribed, the cutter strikes 01f a box fromjth'e tube. A friction-roller, I, mounted on a short stud projecting from the lower partof the cutter-plate K, projects into a cam-groove, L, in the face of thewheel L.

When the tube i s projected, that part of the groove marked '1 acts onthe roller 1, and

causes the cutter to swing up against the bottom of the tube, cutting ithalf. through close to the end of the mandrel and to the frameopening,thus making a shear-cut, and not crushing or altering the shape of thetube. After this first cut the part l of the groove acts on thecutter-roller, causing the cutter to make a cut from the top downward,meeting the first cut, and thus completely severs the box from the tube.

The roller 1 now is acted upon by the part i of the groove, which leavesthe cutter in the position in which it rests when not in operation, withits opening 76 opposite the opening in the frame, to allow the tube tobe projected centrally through it. While in this position the rollerruns in the regularly-curved part of the groove, which extends from the"termination of the part 1 to the beginning of the part P. A strip ofpaper, w, of the proper width to form the box-bottoms, is wound upon aroller, N, mounted on a stud-shaft, n projecting laterally from an arm,N This arm is securely attached to a reciprocating casing, N in whichworks a plunger, N, as will hereinafter be explained." The strip a ispassed through a guide, of, and between feeding-rollers N 4 n, the guidebeing secured to a bracket, 0, and the feeding-rollers mounted on shaftsprojecting therefrom. The bracket 0 is secured to the arm N or to thecasing N The roller N it will be seen, has a long bearing or sleeve,terminating in a ratchetwheel, 0, by means of which the feed of thestrip is gaged and regulated. After the strip passes betweenthefeeding-rollers it enters a guide, 0 secured on the plunger-casing,whichguide conducts it to an opening'in the top of the casing, through whichopening the strip passes, to be acted on by the plunger-first, to cut 0da section for a box-bottom, and then to place it in the end of the tube.A lever, 0 is fulcrumed, with a long bearing, 0 on a shaft, 0 projectingfrom an arm, 0 This lever is curved and caused to hear at its lower end0 upon the edge or periphery of a camwheel, 0 (fastened on the mainshaft B,) by

the action of a spring, 11 coiled upon the bearing 0"", one end of thespring resting against the lever, and the other against the cam-wheel 0As the projection passes from under the lever it is rocked back to itsnormal position by the spring 19 leaving the pawl in position to resumeits action, when another revolution of the cam or main shaft brings thecam in position to operate again on the lover. The space between theratchetteeth is such as to feed the strip into the easin g-where it fitssnugly--a proper distance to be cut off and form a bottom piece of therequired size by each partial revolution of the ratchet-wheel. A springbearing on the roller N prevents the strip from unwinding too freely.The arm 0 is pivoted in lugs on the base A of the frame.

A friction-roller, pion a stud-shaft projecting from this arm bearsagainst a cam-flange, P, on a wheel, P fastened to the main shaft. Theroller is kept against the cam by means of a strong spring, P one end ofwhich bears against the upright A of the frame, and the other againstthe rocking arm 0 to which the roller is secured. This arm is slottednear its upper end to receive a pin secured to the plunger-casing N Theplunger is secured, by means of a pin, T to a rocking arm, R, pivoted inlugs on the base A of the frame, the arm being slotted near its upperend to receive the pin. This arm is provided with a stud-shaft carryinga friction-roller, which is caused to bear against a cam-flange, R, onthe face of the cam-wheel O, by means of a strong spring, R one end ofwhich bears against the upright A of the frame, and the other endagainst the arm R.

1 When the strip of paper a has been properly I fed into the casing,(beyond the end of the plunger,) as before described, an inclinedprojection, W, on the cam-flange P of the wheel P begins to act ontheroller 1), rocking the arm 0 and causing the casing N 2 to move -towardthe paper tube, carrying with it the paper strip 12. (and other partsconnected with the casing,) the bent end 0 of the lever O sliding acrossthe regular portion of the periphery of the cam-wheel O. This movementof the casing continues, as theroller is acting on the inclined part ofthe projection Soon after the beginning of this movement, an inclinedprojection, B on the camflange R of the wheel 0 is presented to theroller 1, and, as the shaft B is revolved, causes the plunger N to slidein its casing N When the plain portion, at the termination of theincline T is presentedto the roller 12 the casing has been moved forwarduntil its end rests against the upright A of the frame, the

enlarged or shouldered part 4 of the casin g fitting over the end of thepaper tube. (See Fig.

16.) During this time the plunger has been advancing, and when the casing rests against the upright A the plunger cuts 011' the strip n a pieceto form the box-bottom. This cutting is efi'ected by the upper edge ofthe end of the plunger acting with the edge of a cutter-plate, B securedupon the casing on the side of its top opening, through which the strippasses, as before described, the casing bein g now at rest, and theroller p acting on the regular surface or plain portion of theprojection T the plunger continuing to move in the casing, pushing alongbefore it the bottom piece, and finally forcing it into the endofthetube, (which has been gummed and slightly advanced, as hereinbeforedescribed without altering the shape of the tube, as it is supported onits outside by the enlargement 1 of the casing-opening, fitting overthetube.

As the cam-shaft B continues to revolve,

The parts are now in position for the repetition of the above-describedoperation as the .shaft B revolves, so as to present the projectionsagain to the rollers. that the bottom forming and applying -mech- Duringthe time anism is at rest the tube is projected and a box struck off, asbefore described.

The tops for the boxesare formed by a machine similar to the one abovedescribed, and may be equal in length to the box, so as to form asliding inclosing cover, or may be made short, like an ordinarytop.

The boxes may be made with projecting bottoms, if desired, thebottom-formin g casingand plunger being made large enough to producebottom pieces of the desired size, thestrip-feedingdevicescorrespondinglychanged,thepaster being soconstructed as to apply the paste to the end instead of inside of thetube, and the bottom being presented to the end of the tube instead ofinserted in it.

By changing the form of the mandrel, and

correspondingly altering the forming-rollers,

mandrel-casing, and bottom-forming devices,

boxes of different shapes may be manufactured.

Instead of the knife-cutter herein described, to sever the boxes fromthe tube, rapidly-revolving circular saws may be employed, and be swungup automatically to the tube from opposite directions to strike of theboxes.

The main or cam shaft is shown, in this instance, as revolved by ahand-crank; but it is obvious that themechanism may be driven byanysuitable motive-power. It is also 0bvious that the same set of cams maybe employed to operate two or more machines, and thus the rapidity withwhich the boxes may be manufactured increased.
